Rising alt-rock act Keo released their first EP Siren in June 2025, spearheaded by single I Lied, Amber. The song is a powerful debut statement by the London band, combining raw, powerhouse vocals with complex layers of shoegaze-y guitars and a pummeling rhythm section. The grungy sonics take cues from legends like Jeff Buckley and Radiohead, while adding a modern twist that makes the track distinctly Keo.
